Thanks for updating. Glad to hear she's doing a little better today, although it does sound as if she's still suffering some unexpected effects. Ketamine is a bit of a nasty drug for small animals in my limited experience, although combined with the xylazine it should have been OK. One thing I can't see on there is the reversal drug? I would have expected atipamezole or yohimbine to be on there as well, unless they don't include that in their pricing...? It could be that she came round post-operatively on her own and so they didn't use it, it just struck me as a little odd as in my experience using xylazine, we've always reversed it.

Has she passed any more urine since last night? Another vet trip is definitely in order when you can, hope you can get to the bottom of it!
